"Chess, due to its educative qualities, became a necessity to the modern man. The game's growing popularity all over the world confirms this.
The game of chess developers a peculiar kind of thinking which I would call "the chess thinking". It is just such thinking that is necessary to the man of the atomic age."

Alexander Matanovich, grandmaster

"A chess player who has analyzed deeply at least one of his games, will inrush himself more than the one who will play a dozen games without recording them."
